Let hh be in the Cartan subalgebra. Let (α1,,αn)\left({\alpha}_{1}, \dots, {\alpha}_{n}\right) be simple roots with respect to h. Then the hh-characteristic, as defined by E. Dynkin, is the nn-tuple (α1(h),,αn(h))\left({\alpha}_{1}{}\left(h\right), \dots, {\alpha}_{n}{}\left(h\right)\right).

The actual realization of h. The coordinates of hh are given with respect to the fixed original simple basis. Note that the hh-characteristic is computed using a possibly different simple basis, more precisely, with respect to any h-positive simple basis.
A regular semisimple subalgebra might contain an sl(2)sl{}\left(2\right) such that it has no centralizer in the regular semisimple subalgebra, but the regular semisimple subalgebra might fail to be minimal containing. This happens when another minimal containing regular semisimple subalgebra of equal rank nests as a root subalgebra in the containing subalgebra. See Dynkin, Semisimple Lie subalgebras of semisimple Lie algebras, remark before Theorem 10.4.
The sl(2)sl{}\left(2\right) submodules of the ambient Lie algebra are parametrized by their highest weight with respect to the Cartan element hh of sl(2)sl{}\left(2\right). In turn, the highest weight is a positive integer multiple of the fundamental highest weight ψ\psi. Vkψ{V}_{k \psi} is k+1k+1-dimensional.

Length longest root ambient algebra squared/4= 1/2

Given a root subsystem PP, and a root sub-subsystem P0{P}_{0}, in (10.2) of Semisimple subalgebras of semisimple Lie algebras, E. Dynkin defines a numerical constant e(P,P0)e{}\left(P, {P}_{0}\right) (which we call Dynkin epsilon).
In Theorem 10.3, Dynkin proves that if an sl(2)sl{}\left(2\right) is an SS-subalgebra in the root subalgebra generated by PP, such that it has characteristic 2 for all simple roots of PP lying in P0{P}_{0}, then e{}\left(P, {P}_{0}\right)=0e{}\left(P, {P}_{0}\right)=0.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens here.
